Parallel Learning Portfolio-Based Solvers

From LRDE

Abstract

Exploiting multi-core architectures is a way to tackle the CPU time consumption when solving SAT- isfiability (SAT) problems. Portfolio is one of the main techniques that implements this principle. It consists in making several solvers competing, on the same problem, and the winner will be the first that answers. In this work, we improved this technique by using a learning schema, namely the Exploration- Exploitation using Exponential weight (EXP3)that allows smart resource allocations. Our contribution is adapted to situations where we have to solve a bench of SAT instances issued from one or several sequence of problems. Our experiments show that our approach achieves good results.
